Introduction to Angular

Introduction to Angular
So what is Angular, and why would you want to use it? The simplest answer to that question is that Angular is a JavaScript library, but it's so much more than that. It's probably more accurate to categorize it as an MV* framework. Angular isn't just an MV* framework, it's an opinionated MV* framework. What is opinionated software? Well, opinionated software guides you into certain ways of doing things. Opinionated software has a vision. It may limit itself to solving fewer problems, but generally, software with opinions solves those problems with less fuss. That doesn't mean that there isn't more than one way to solve a problem with Angular. For example, take DOM manipulation. Angular wants you to only manipulate your DOM inside of directives, but with Angular, inside of a directive you can use jQuery, Zepto, any other library, or even just raw JavaScript to manipulate your DOM. That doesn't mean that you can't manipulate the DOM from within any other piece of an Angular application, but Angular definitely has an opinion about whether or not you should, and it gently guides you into doing things a certain way.

Let’s make sure that we understand exactly what an MV* framework is.
